Ultracold Atoms in a Tunable Optical Kagome Lattice
Geometrically frustrated systems with a large degeneracy of low energy states are of central interest in condensed-matter physics. The kagome net - a pattern of corner-sharing triangular plaquettes - presents a particularly high degree of frustration, reflected in the non-dispersive orbital bands. The ground state of the kagome quantum antiferromagnet, …
